DUST-GUARD.

SPECIFICATION forming part of Letters Patent No. 571,354, dated November1'7, 1896. Application filed May 8, 1895. Serial No. 548,479. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, DANIEL FocER, a citi- 'zen of the United States,residing at Cape May city, in the county of Cape May and State of NewJersey, have invented certain new and useful Improvements in Adjustableand Portable Dust-Guards; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain new and useful improvements incar-axle boxes, and has for its object the formation of an adj ustableand portable dust'guard, which is specially adapted to prevent theentrance of dust into the axle-box and its consequent mixing with thepacking material, thus by friction causing the journals and brasses tobecome heated, and which at the same time will be more simple in itsconstruction, more easy and quick of adjustment, and more satisfactoryin its working than any similar device now in use.

To this end my invention consists in the construction described in thefollowing specification and set forth in the accompanying drawings, inwhich-- Figure 1 shows a longitudinal section through the axle-box,showing an edge view of the guard in position. Fig.2 is a transversesection of the axle-box, showing a front view of the guard in position.Fig. 3 is a detached perspective View of the guard.

The device itself, as shown in Fig. 3, consists of a plate A of a sizesuited to the size of the axle-box and the journal or shafting to whichit is to be fitted, and having a portion as at D, to accommodate thejournal. The plate is rounded at the lower corners, and on the underside has preferably a semielliptic spring attached thereto, which bearsat its ends against the bottom of the axle-box and serves to keep theplate at all times snugly up against the axle or journal.

In the ordinary construction of oar-axle boxes the wear upon the brassesand the back plate of the axle-box is above the journal, all

the pressure being exerted upon the journal from that direction.Consequently while the box may fit tightly to the journal above the samethere will be a constantly-increasing opening in the back plate of thebox below the journal, as shown at H in Fig. 1. It is the purpose anddesign of this invention to form a device such as shown which willeffectually close this opening and at the same time adjust itself to theupward wear of the journal against the back plate of the axle-box.

In the form of my invention shown in Figs.

- 1 and 3 the front and back faces a a of the dust-guard are preferablymade of asbestos with an interposed filling b of wood fiber. I may,however, substitute for the latter a metal plate, if desired. The guardis also formed with a handle 0, which is designed to facilitate itsadjustment and removal.

By reason of the great simplicity of this dustguard it can be verycheaply constructed, and instead of forming the axle-box withspecially-constructed grooves or ledges to adapt it to the forms ofaxle-boxes of ordinary construction it will be noted that the dust-guardabove described is capable of immediate and easy adjustment to anyaxle-box now in use on the railroads of this country, it only beingnecessary to raise the lid of the axle-box, remove the packing, insertthe guard under the journal, and push it into place by means of apacking-hook or other instrument; or in case it becomes necessary toreplace the guard by another it can be easily removed by inserting thepacking-hook into the loop or handle G and withdrawing the guard fromthe box.

This invention is designed not only for a dus t-guard to exclude dustfrom the axle-box, but also serves to prevent undue Waste of thelubricating-oil and also to prevent the oil from flowing out under thejournal and defacing the wheels and truck-frame.

Although I havedescribed and shown my invention as applied especially tocar-axle boxes, it is to be understood that it may be used with any formof journal-box such as are used on street-cars, or on dynamos, or

machine-shafting of any kind.

Having thus described my invention, what boX and provided on its frontface with a handle by which the guard may be readily Withdrawn from thebox, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
